Philip Reames 059722da5e Revert "[RISCV] Default to MicroOpBufferSize = 1 for scheduling purposes (#126608)" and follow up commit. 
This reverts commit 9cc8442a2b438962883bbbfd8ff62ad4b1a2b95d.
This reverts commit 859c871184bdfdebb47b5c7ec5e59348e0534e0b.

A performance regression was reported on the original review.  There appears
to have been an unexpected interaction here.  Reverting during investigation.
